Shaping boundaries to control and transport topological defects in colloidal nematic liquid crystals
Gerardo Campos-Villalobos, André F. V. Matias, Ethan I. L. Jull +2
Anisotropic rod-like particles form liquid crystalline phases with varying degrees of orientational and translational order. When confined geometrically, these phases can give rise…
Dynamic bidirectional coupling of membrane morphology and rod organization in flexible vesicles
Stijn van der Ham, André F. V. Matias, Marjolein Dijkstra +1
The ordering of rod-like particles in soft, deformable containers emerges from the interplay of anisotropic interactions, geometric confinement, and boundary compliance. This compe…
From Knots to Crystals: Machine-Learned Potentials for Self-Assembling Topological Solitons in Liquid Crystals
Arunkumar Bupathy, Darian Hall, Ivan I. Smalyukh +3
Knotted fields in classical and quantum systems have long been recognized for their non-trivial topologies and particle-like behavior, but practical applications have been limited…
Surface Charge Relaxation Controls the Lifetime of Out-of-Equilibrium Colloidal Crystals
Laura Jansen, Thijs ter Rele, Marjolein Dijkstra
Interactions between charged colloidal particles are profoundly influenced by charge regulation and charge renormalization, rendering the effective potential highly sensitive to lo…
Machine learning many-body potentials for charged colloids in primitive 1:1 electrolytes
Thijs ter Rele, Gerardo Campos-Villalobos, René van Roij +1
Effective interactions between charged particles dispersed in an electrolyte are most commonly modeled using the Derjaguin-Landau-Verwey-Overbeek (DLVO) potential, where the ions i…
Ion Selectivity in Uncharged Tapered Nanoslits through Heterogeneous Water Polarization
Tim Veenstra, Gerardo Campos-Villalobos, Giuliana Giunta +2
We employ molecular dynamics simulations to investigate ion and water transport driven by an electric field through quasi-two-dimensional nanoslits with a tapered geometry. Despite…
